Although the timing and extent of a whole-genome duplication occurring in the common lineage of most modern cereals are clear, the existence or extent of more ancient genome duplications in cereals and perhaps other monocots has been hinted at, but remain unclear. We present evidence of additional duplication blocks of deeper hierarchy than the pancereal rho (rho) duplication, covering at least 20% of the cereal transcriptome. These more ancient duplicated regions, herein called sigma, are evide ...[more]
